CARTON-HINGIHG MACHINE.

Application filed March 13, 1924. Serial No. 698,988.

This invention relates to a carton hinging machine particularly adaptedto apply hinges t flexible material, such as tough paper, muslin or thelike, to cartons constructed of heavy paste-board, or similar material,and containing a large number of boxes, pouches, or packages ofcigarettes, or of similar commodities. In packing cig arettes for themarket, groups, usually of or 20, are packed, either in tin orcard-board boxes, or in paper pouches which are open at one end, or inpaper packages which are closed at both ends. These boxes, or pouches,or packages, as the case may be, are then packed in cartons constructedof heavy paste-board having cov rs or lids of the same material, andalso having hinges of tough paper. The cartons are then packed in casesof still heavier material, for shipment. The term cartons, as usedherein, has the special meaning which is of necessity associated with itin the industry, in order to avoid constant confusion of the name of thedifferent cigarette containers used. Such cartons go through the machineloaded with cigarette boxes, pouches or packages; and a hinge isautomatically applied to each carton and lid in transit.

Heretofore, so far as I am aware, such 1 hinges have been applied tosuch cartons by means of manual labor. The main object of the presentinvention is the production of a machine to automatically apply flexiblehinges to cartons of the kind mentioned.

luct=on of such a machine which r the hinges not only to the exterior ofthe cartons, but also to their interior, thus forming a double hinge.With these and other objects not specifically mentioned in view, theinvention consists in certain constructions and combinations which willbe hereina't'te-r fully described and then specifically set forth intheclaims hereunto appended.

In the accompanying drawings, which form a part of this specificationand in which like characters of reference indicate the same or likeparts, Figs. 1, 1 1 and 1, taken together, illustrate a front elevation.partly in section, of a machine constructed in accordance with theinvention. Figs. 2

Fig. 12 is a sectional plan viewtaken on the line 1.2-4.2 in Fig'."11.' -And Fig. 13 is an end elevationof the carton closing mechanism.

In carrying the invention into efiect, there is provided a source ofcarton supply, a source of hinge supply, and means for successivelyassembling cartons and hinges drawn from said sources. structions, theassembling means "includes mechanism for successively forwarding thecartons from the source of carton supply to the assembling position;mechanism for torwarding hinges from the source of hinge sup-.

ply to the assembling position; mechanism for supplying adhesive to thehinges; mechanism for pressing the adhesivehinges against the cartons;mechanism for applying heat to the cartons and hinges at theirjunctionto dry the adhesive; mechanism for opening each carton after ahinge has been applied to its exterior, in order that a hinge may bethereafter applied to its interior; and mechanism for closing eachcarton after a hinge has been applied to its "interior. The abovementioned sources, means and mechanisms maybe widely varied inconstruction within the scope of the claims, for theparticulardevice'selected to illustrate the invention is but one of manypossible concrete embodiments of the same. the invention, thereforaisnot lee In the best constrictcd to the precise details of the structureshown and described. Furthermore, certain parts of the machine arecapable ot'use inde pendent of other parts, and such independent use iscontemplated.

The invention contemplates the use of a source of carton supplyincluding mechanism {or so supporting a stack of cartons that they maybe successively removed from the bottom of the stack. As shown, thismechanism includes a bottomless magazine consisting of flat uprights14,15 and angular uprights 1 617, all supported on a bracket 18, boltedto the end of a bed plate 19, which is the nia'in'bed plate of themachine. The uprights of the magazine are held in proper spaced relationby means of straps 20'21, riveted or otherwise secured thereto; and thewhole magazine structure leans a little in the direction in whichcartons are removed therefrom. Resting upon the upper surface of thebracket 18 below the bottom of the magazine are two wooden blocks 22,one at either side of the magazine; and just above the front block 22there is hinged to the corner of the magazine a s1' 1'-in.g-prcssed gate23. The blocks 22, the angular upright 17, and the gate 23 coac't- "toproperly locate the lowermost carton of the stack in the magazine, sothat it will be properly engaged by forwarding mechanism which-takes itfrom the bottom of th'e magazine and transfers it to assemblingposition, and thence out of the machine. The tensionof the torsionspring 24 of the gate 23 is sufficient to hold the lowermost cartonwithin the confines of the magazine against accidental displacementuntil the proper time arrives to remove the carton from the magazine.lVhen that occurs, the gate 23 swings open, permits the car-ton to pass;and after the carton has passed, it swings back to its normal position,as shown in Fig. 2.

it is necessary to support all of the can tons in the stack while thebottominost carton is being removed therefrom, and this is effectedby-det'ent devices"2 "-25, fulcru-mcd on studs 2626, secured in thebracket 18 before referred to. The detent devices 2"-25 are furtherprovided with inwardly extending arms 27-27, each carrying a roller 28.Each of the detent devices is further provided with a short lug 29normally contacting with an adjusting screw 3'0. threaded in a bearingcarried by the bracket 18. The two detent devices are con nected bymeans of a tension spring 31 which normally operates to hold the lugs 29against the adjusting screws 30, and thus maintain-the free ends of thedetent devices in their iproperposition between the lowermost carton andthe one immediately above it.

For the purpose of- .forwarding cartons from the magazine or othersource of carton supply to assembling position, there is provided aconveyor having carton engaging devices WlllCll successively come incontact with cartons in the source of supply and force them outtherefrom. As vshown, this conveyor includes a chain 32' provided with aseries of carton engaging devices or lugs 33. In Figs. 1 and 2-, theupper run of the chain 32 moves toward the right, and the lugs 33 are sospaced with relation 'to tee arms 27 that one of said lugs comes incontact with the rollers 28*28 immediately after the lowermost carton ofthe stack in the magazine has been removed therefrom. As the lug 33moves forward, the detent devices 2525 are swung outwardly on theirfulcrums until they are clear ottherthen lowermost carton of the stack.The .whole stack then drops until the lowern'iost carton rests on theblocks 2222. stack has dropped, the lug Siipasses out of engagement withthe rollers 2828, and the spring 31 causes the detent devices to againcome into position between the lowermost carton and the oneiuunedi'ately above it, in readiness to support the stack during thenext carton removing operation.

As soon as the As the lugs successively push the car- 7 tons from thebottom of the stack in the magazine, they move them into a horizontalpathway extending along the machine. This pathway is provided with adouble series of large carton engaging and supporting rollers 34. Thepathway is further provided with a series of smaller rollers 35 carriedin a irame 36 mounted on the bed plate 19. It

may be here remarked that in the use of the machine shown for hingingcigarette cartons, the cartons come to the machine loaded with paeiia esand with the lid in place on the body oi tne carton. The purpose of theupper rollers 35 to hold this lid in place as the carton is t'orw-ardedby the chain 32 and lugs 33. r

The forwarding means or chain is given an intermittent or step-by stepmovement in order to successively move the cartons from the ma-gazinetoa position where a hinge is applied exteriorly thereto; thence to a position where the lid is opened; thence to a position where a hinge isapplied interiorly. to the carton; thence to a position where the lid isagain closed; and thence out otthe machine. The chain runs idly over asprocket 37 adjacent the-magazine; it also runs over and driven by asprocket 38 at the other end of the machine and test on a shaft 3 (seeFigs. 1"; l1 and 12), The shatt llfi engaged by two rollers carried atopposite ends of "a lever 46 fulcrumed on a stud l7 secured in themachine frame by n'ieans of a nut l8. Fast to the hub of the lever/l6 isa :i'procket -il-9 over which runs a chain 50 which 'drii 'es the saidsprocket. Also fast on the hub of the lever 46 is an'adjustable cam 51which is in constant engagement With a cam bowl 52 formed on one end ofa lever '53 which is fulcrumed on the stud 47 before referred to. Theopposite end of the lever 53 l as a lug 54 acting a locking pawl inconjunction with an adjustable plate 55 havlocking notches 56 in itsperiphery. This plate is fast on the pinion 49 before referred to. Thefunction of the lug 54: is to lock the forwarding chain againstaccidental displacement while a series of cartons is in position andbeing acted upon at the several stations at which they stop on theirtravel through the machine.

The chain 50 runs over and derives its motion from a sprocket 57 (seeFig. 7) fast on one end of a shaft 58 journaled in a suit able bearingin a bracket 59 depending from the bed plate 19. The other end of theshaft 58 carries a bevel gear 60 which is in mesh with and driven by asecond bevel gear 61 fast on a shaft 62 journaled in suitable bearingsin the frame of the machine. Near the right end of the machine, theshaft 62 carries a slip clutch gear which is in mesh with and driven bya pinion 64 formed on the end of a short shaft extending out beyond themachine frame and carrying on its projecting end a fast and loose pulley65 and The belt shifting device 67 is provided for shifting the drivingbelt 68 in a well known manner. By means of the structure so fardescribed, the cartons are successively moved from position of rest toposition of rest in their travel through the machine. v

After leaving the magazine a carton comes to rest first in position tobe assembled with a hinge, with the latter applied exteriorly to thecarton. A source of hinge supply is located adjacent this assembling"position and. as shown, it includes an inclined bottomlcss magazine 69supported by brackets to and Tl rising from the bed plate 19. In themachine shown. the hinges are strips of tough paper. and a stack of themrests on the inclined surface of the magazine with the lower end of thestack under two s' 'iring fingers T2-73 and engaged by knife-edgeddetents Tel of well known construction and operation. Ordinarily a blockor weight, not shown, is placed in the magazine above the hinges inorder to move the stack down to the detents 7 as the hinges aresuccessively removed from the magazine. Referring particularly to Fig.4. CB indicates a carton body resting on one of the rollers 34 of thepathway before referred to, and CL indi- ("ates the lid of the carton inposition on the body. It will be noticed that the outer peripheralsurface of the lid is offset from the outer surface of the body of thecarton.

This obviously adds to the difficulty of apposition, and for thispurpose there is provided an adhesive fountain supported by the brackets70 and 71 before referred to. Vorklng in this fountain is an adhesivedistributing roller 76, and an adhesive applying roller 77 which takesadhesive from the distributing roller and rolls it on a hinge as thelatter is caused to pass said applying roller at equal surface speedtherewith. The distributing roller 7 6 rotated by a gear 78 on itsshaft, which in turn is rotated by a pinion 79 on the shaft 80 of theapplying roller. The other end of the shaft 80 carries a gear 81 whichis in mesh with and driven by a gear 82 fast on one end of a short shaftjo-urnz-iled in the bracket 70 and carrying a sprocket 83 over whichruns a driving chain 84L which derives its motion from a shaft 85journaled in suitable hearings in the main frame of the machine belowthe bed plate 19. The shaft 85 derives its motion from the main powershaft through the agency of a sprocket and chain connection 86.

In the machine shown, the mechan sm for forwarding hinges from thesource of hinge supply to assembling position includes a suction hingecarrier and operating connections. This suction. hinge carrier is in theform of a hollow rectangular perforated head S'Twhich is mounted on oneend of a tube 88, slidably mounted in bearings 89 and 90 formed on abracket 91, the latter being fast on a short shaft 92 journal-ed in abracket 93 rising from the bed plate 19 before referred to. To the farend ofthe shaft 92'is clamped an arm 94, and the free end of this arm ispivotally connected to one end of a connecting rod. 95, the other 6 Iend of this rod being connected to the free end of a cam lever 96.fllllilllll'lOtl at 97 to a bracket 98 secured to the side of the bedplying roller (as indicated in the upperiii) . complished byreciprocating the tube 88. To

this end, the tube 88, at its end opposite the suction head 87, carriesa head 101 provided with a cam bowl 102 which tracks in a cam groove 103formed in an arm 104 fast on one end of ashort shaft 105 journaled in abracket 1013 rising from the bed plate 19 before referred to. Clamped tothe other end of the shaft 105 is an arm 107, the free end "of which isconnected to one end of a yieldable connecting rod 108 of well knowncon.- structi'on and operation, the other end of this connecting rodbeing pivoted at 109 to a cam lever 110 fulcrumed a t 111 to the bracket98 before referred to. The cam lever 110 carries a cam bowl 112 trackingin a groove in one side of the cam 100 before referred to. By means ofthe structure just described, the suction hinge carrier head 87 is givena slight movement toward the lowermost hinge in the stack in themagazine when the bracket 91 is in the position shown in Fig. 4. Suctionbeing on, the lowermost hinge in the stack adheres to the carrier whichthen retreats slightly to pull the adhering hinge from the stack. Thehinge carrier then swings down past the adhesive applying mechanismwhich rolls adhesive upon the exposed surface of the hinge as thecarrier moves by the applying roller 77. Then when the hinge carrier hasrea'chedthe position shown by the lowermost broken lines in Fig. 4, thesuction head is given a slight outward movement to press the hingebearing the adhesive against the side of the carton lid and against theside of the carton body adjacent thereto to cause said hinge to stick toboth the body and the lid. Then the suction is out off by mechanism tobe presently described, so that when the suction head again retreats itwill not pull the hinge off of the carton. The mechanism for controllingthe suction includes a valve casing 113 held on the tube 88 by means ofnuts 114. The valve casing is provided with a. valve chamber 115, andinthis chamber is located a valve 116. This valve is provided. with a stem117 carrying at its upper end a pinion 118 which is in mesh with asector 119 fulcrumed "on a stud 120, the la'tter being fast in. a boss121 formed on the casing 113 before referred to. As the swinging bracket91 approaches one end of its movement, the sector 119 comes in contactwith an adjustable stop 122 carried by the bracket 93 before referredto.

As the bracket 91 approaches the other end of its movement, the sectorcomes in contact with a similar adjustable step 123 mounted on a bracket124 bolted to the top of the bracket 93 before referred to. By thismechanism the valve is thrown from open to closed position at one end ofthe path of movement of the bracket 91, and from closed to open positionat the other. Suction is established within the tube 88 and hingecarrier head 87 through the agency of a hose 125 connected with asuitable suction producing mechanism, not shown but of well knownconstruction and operation.

A trip mechanism is provided for the purpose of preventing theapplication of adhesive to the suction head of the hinge carrier in theevent that no hinge is lying thereon. This trip mechanism is vacuumcontrolled. To this end a hose 126 is provided, one end of thishosebeing incommunication with one end of the valve cham-' her 115, and theother with the interior of a vacuum chamber 127, one side of which iscovered by a flexible diaphragm 128, the diaphragm being mounted on oneend of a short arm. 129 fast on a short shaft 130 journaled in a bracket131 in which the vacuum chamber 127 is formed. The shaft 130 alsocarries a trip arm 132. This arm is normally pulled downwardly by atension spring 133 connecting it with a post 134 fast in the side of thebed plate 19 before referred to.

lVhen a hinge is in proper position on the suction head 87, a partialvacuum is created, not only in the tube 88 but in the vacuum chamber127. In this event, the atmospheric pressure acting on the diaphragm 128depresses the latter, and this results in lifting the trip arm 132against the resistance of the spring 133. hen, however, there is nohinge on the suction head 87, the interior of r the tube 88 will be opento the atmosphere and a vacuum will not be produced in the vacuumchamber 127; and in that event, the trip arm will remain where it is. Bythis means the swinging inovement of the cam arm .104 and thelongitudinal .movement of the tube 88 will be greater or less inaccordance with the position of the trip arm 132 in or out of the pathof movement of the arm 104, it being recalled that the connecting rodl08-which operates the arm 104-is of a yielding character; so that,although the movement of the cam lever is alwaysfhe same, the movementof the cam arm 104 is dependent upon the position of the trip arm Assoon as a hinge has been applied to the exterior of a carton, the lattermoves along toward a position where it is opened; and while movingtoward that position, the hinge is subjected to pressure and to heat tocause it to become firmly attached to the carton body and lid before thecarton is opened. As shown, the pressure device includes a series ofbrushes 135, 136 and 137 rotating on vertical axes alongside the pathwayfor the shaft before referred to.

carton. For the purpose of driving these brushes, there is provided ashort shaft 138 driven by means of a sprocket chain 139 from the shaft85 before referred to. The shaft 138 carries a bevel gear 140 whichdrives'a bevel gear 1 1-1 on the lower end of the spindle which carriesthe rotating brush 137. The spindle of the brush 137 carries a gear 142which meshes with a pinion 143 on the spindle. of the brush 136. Thepinion 143 meshes with and drives a gear 1&4 on the spindle of the brush1.35. By this means two of the brushes are driven in one direction, andthe other in the opposite direction.

To permit the leading edge of a hinge on an advancing carton to passbeyond the point where the brush 135 operates,the'latter is movabletoward and away from the pathway, Just before a carton reaches the brush135, the latter swings out of the way and remains out of the way untilthe leading edge of the hinge on the carton has reached a point betweenthe brushes 135 and 100,

then the brush 1.35 swings back on to the hinge, and the two brushes 135and 136, one rotating in each direction, coact to smootl and press thehinge in place on thecarton body and lid. The mechanism by means ofwhich the brush 135 is moved in and out of operative position is asfollows The spindle of the brush 135 is mounted in a swinging frame 145which is fulcrumed on the axis of the brush 136. A connectingrod 146connects the swinging frame 145 with the upper arm of a lever 147projecting upwardly through a suitable aperture in the bed plate 19 andfulcrumed at 148 below said bed plate. The other end of the lever 147'carries a cam bowl 149 tracking on a cam 150 fast on the The cam bowl14-9 is held against the cam 150 by the action of a tension spring 151of well known construction and operation.

7 As soon as an advancing carton has passed the brushes just described,it comes within the range of action of an electric heating device 152,the operating surface of which contacts with he hinge already applied tothe carton body and lid and operates in a well known manner to dry theglue.

After the exterior hinge has been thus applied to the carton and lid,the carton comes to rest in position to be opened in order that aninterior hinge may be applied and in order to permit final inspection ofits contents. As shown, the carton opening mechanism includes a latch153 fast on a short shaft 154 journaled in suitable bearings 155, 156formed on the end of an inverted U- shaped arm 157. This arm isfulcrumed on a short shaft 158 journaled in a bearing 159 supported bythe bed plate 19 before referred to. Pivoted to the upper part of thearm 157 at 160 is one end of a connecting rod 161, the other end-ofwhich is connected to a cam lever 162 fulcrum-ed at 163 on a studcarried by a bracket 16 1 depending from'the bed plate 19 beforereferred to. The lower end of the cam lever 162 carries a cam bowl 165tracking in a suitable groove in a cam 166 fast on the shaft 652 beforereferred to.

By means of the structure just described, the latch at the proper timeengages the lid on the side of the carton opposite the hinge, lifts it,and throws the lid back to open position. Then, after the then opencarton has been moved out of the way, the arm carrying the latch swingsback to engage the lid of an oncoming carton and open it in the sameway. i

For the purpose of holding the carton fi mly while the lid is beingopened, mechanism for clamping the carton body is pro-V vided and, asshown, this includes-a bar 167 against which the hinge side of thecarton rests. It further includes a clamp 168 normally occupying theposition shown in Fig. 8. This clamp is formed in the end of an arm faston a short shaft 169 jo-urnaled in a bracket 170screwed to the top ofthe bed plate 19. Upon the other end of the shaft 169 is fixed a cam arm171 which is engaged by a cam bowl 172 on the arm 157 when the parts arein the position shown. in Fig. 8. A torsion spring 173 coiled around theshaft 169 serves to cause the clamp 168 to swing into engagement with acarton and hold'it as soon as the arm 157 moves upwardly and the cambowl 173 pern'iits the lever 171 to swing in.

From carton opening position, the carton is forwarded to a positionwhere a hinge is ap plied interiorly. Means employed for this purpose isa duplicate in all essential particulars with that used for applying ahinge exteriorly, and since a description of one an swers for adescription of the other the description of the second mechanism of thischaracter is omitted in the interest of brevity andclearness.

After an interior hinge has been applied to the carton, the latter isthen advanced to a position where it comes within therange of action ofa mechanism for pressing the adhesive hinge hard against the inside ofthe lid. This pressing mechanism con sists of a flat plate 174 mountedon a shortlsliai't 175 journaled in bearings in the ends of overhangingarms 17 61 76 bolted to the machine frame. The shaft 175 projects beyondone of the bearings 176, and upon its pro jecting end it carries an arm177. The free end of this arm carries a roller 178 operating against theface of an upright lever 179. This lever is fast on a shaft 180 whichruns along the machine just above the bed plate 19. to a posit on at theleft of the opening a gear 182 on the shaft 158 before referred to; Itwill be recalled that this shaft .158

is operated by the cam lever 162. lVhen this occurs, the gear 182 willoperate the sector ear 181 which in. turn will oaerate the t) 7 shaft180. The roller 1Y8 is'held against the lever 179 by the action of atension spring 183.

"Fromthe position where the inner hinge 1s pressed againtt the lid, thecarton is advancedinto the range of action of lid closling mechanism.11s the carton is advanced with its lid open, the lid slidesalong-atrack 18 1 and off of that on 'to a shorter track 185, mounted ona bracket 186, bolted to the machineframe. The lidclosin-g mechanismincludes ,an arm 18? having a'T head 188 is .and a hub 189, loose on theshaft 180 before referredto. This hub has a step-connection with'acollar 190 fast on the shaft 180 before referred to, so that itsmovement in one direction. willbe positive. lts'movement in the otherdirection is controlled by means or a torsion spring 191 coiled aroundthe shaft 190 and engaging the hub 189 and the hub of the arm 1 79. 1Vhen the shaft 180 is rocked-by mechanism heretofore described, the arm18?, which normally rests behind and below the track 185, moves upwardto 'engngethe lid, and "then. over to throw it over on :to the top ofthe carton body.

From the position of carton closure, the cartons are successivelyejected from the machine, preferably directly into a wrapping machinewhich automatically wraps the linished carton.

It will of course be understood that the second or internal hingeapplying mechanism is not always necessarily in use.

In view of the foregoing, a detailed des ription of the operationof thedevice is believedto be unnecessary and is. therefore oinittedin theinterest of brevity.
